Exploration and augmentation of pharmacological space via adversarial auto-encoder model for facilitating kinase-centric drug development

Abstract: Predicting compound–protein interactions (CPIs) is of great importance for drug discovery and repositioning, yet still challenging mainly due to the sparse nature of CPI matrixes, resulting in poor generalization performance. Hence, unlike typical CPI prediction models focused on representation learning or model selection, we propose a deep neural network-based strategy, PCM-AAE, that re-explores and augments the pharmacological space of kinase inhibitors by introducing the adversarial auto-encoder model (AAE)… Show more

“…Our models outperformed the Random Undersampling , Weighted Loss , and Similarity-Controlled methods (Table ). We additionally implemented three types of 5-fold cross-validation recently adopted in CPI prediction and other fields: , Compound cross-validation (CV), protein CV, and compound–protein CV (see Supporting Information Text S2). As shown in Figure S2, our approach performed best in all the CVs, validating our self-training method’s effectiveness.…”

“…The models based on VAE reduct dimensionality to learn latent representations from input data .Therefore they can learn the probability distribution of the dataset and Reproduce the input data as much as possible. [5] CVAE, as a variant of VAE, introduces the concept of conditional vectors after transforming the input data into potential vectors. After decoding by the decoder, compound molecules with target ideal properties can be generated.…”
